How to see if the power supply is enough?

How to check the power supply of the computer host;

1. There is a corresponding sticker label on the power supply shell inside the computer case, and the corresponding input power will be marked on the label.

If you know the power model of your computer, you can also find out the power of the power supply according to the brand and model of the power supply.

Power supply purchase skills:

1. When choosing a power supply, the most important thing is of course the output power of the power supply. The most basic thing for a qualified power supply is to meet the output power required by the computer, that is, the rated power must meet the demand.

2. Pay attention to the output line of the power supply. The first is interface configuration, and there should be enough interface types. For example, the power interface of graphics card is 6/6+2pin interface. If users need to use independent power supply graphics cards, they need to choose enough interfaces according to their own needs. Although the problem of insufficient interface can be solved by switching lines, there are certain security risks in using switching lines.

3. The line length of the power supply should meet the requirements. It is mainly the wiring on the back, and the CPU power cord has the highest length requirement. If the CPU power cord reaches 50cm for the common tower chassis, it can meet the back wiring.

4. The authenticity of the power supply can be identified by the nameplate of the power supply. When choosing a power supply, you should learn to distinguish between authenticity and falsehood. If you accidentally buy a fake and shoddy power supply, it will not only fail to meet the stable power supply demand, but also damage other hardware and cause greater losses. Authentic power nameplates need clear fonts, and the logo can completely indicate the rated power, output current, authentication information and other related information.

5. Anti-counterfeiting label is also an important basis for identifying authenticity. In order to maintain their product image, many brand power supplies will establish anti-counterfeiting systems with anti-counterfeiting labels. It can be queried by SMS, telephone, Internet, etc. to identify the authenticity.

6, weighing can also check the authenticity of the power supply. Under normal circumstances, a good quality power supply will not cut corners because of its excellent workmanship, and its weight is much heavier than that of an inferior power supply. However, it does not rule out that some power supplies with the same good quality may not be heavy. Therefore, the accuracy of such a measure is not high, and it can not be used as the main basis for judging authenticity, but only as an auxiliary reference.
